Abstract
The present application relates to method and system of monitoring liquefied gas in a cryogenic liquefied gas tank having an inner shell and an outer shell and an insulation between the inner and outer shell. An exemplary method includes arranging an array of temperature sensors for measuring a temperature of the inner shell wall at different vertical positions, reading sensors in the array, performing a validity check of the sensors, and using only sensors which passed the validity check only, determining a state of the gas based on the temperature data.
